PRINT-DRIER.

Specification of Letters Patent.

Patented Aug. 11, 1914.

To all whom it may concern:

Be it known that I, BnvnnLY Y. Mourns, a citizen of the United States, residing at Corte Madera, in the county of, Marin and State of California, have invented a new and useful Print-Drier, of which the following is a specification in. such full and clear terms as will enable those skilled in the art to construct and use the same.

This invention relates to a. machine for drying photographic prints and its object is to produce a machine which will be capable of handling a large number of such prints 'and which will so dry them as to take out the curl of the paper.

An object of the invention is to produce a machine which two persons can feed, and which will be capable of delivering the dried prints to a common receptacle out of the way of both the operators.

Another object of the invention is to produce a machine which will have means applied thereto to cause'a. print that may stick to the absorbent belt to be removed therefrom and drop into the chute for the dried prints.

A further object of the invention is to produce a drying drum which can be heated electrically or by means of gas, as may be the most desirable.

An embodiment of the invention is shown in the drawing in which the same reference numeral is applied to the same portion throughout, but I am aware that there are many modifications thereof.

Figure 1 is a plan view machine, Fig. 2 is a side complete. machine, Fig. 3 tion of the machine with drying belt broken away for purposes of illustration and looking in the direction of the arrow, Fig. 2, Fig. 4: is a. plan view in section of a portion of the heating drum showing the location of the gas burner therein, Fig. 5 is a sectional view of a. portion of the heating drum periphery, Fig. (i is a sectional view of a portion of the heating drum periphery in which is installed an-electrical heating unit, and Fig. 7 is a plan view of a portion of the drum in which the electrical heater is installed.

The numeral 1 represents a rectangular base frame from which frame uprights 3 extend, said uprightssupporting a frame having members allel to the base frame.

of the complete elevation of the is an end elevaa portion of the 3, i and 5 in a plane par- The member 5 is thereto.

connected at its ends to the two members 3, and with one of the members 4 forms the support for bearingsb, 7, 8 and 9. The driving motor M is mounted on a board 10 which extends across the top of the frame and which is suitably bolted or screwed to the members 4, 4:.

The bearings 6 t0 9 have the shafts 11 and 12 journaled therein, the shaft 11 having two pulleys 13 and Ll thereon while the shaft 12 has two pulleys l5 and'16 to give the proper speed reduction to the drying belt. The dryin belt 17 passes over the rolls 18 and 19 and around the drying drum )0. The end of the shaft on which the roll l8 is mounted has a pulley 21 thereon, and in turn extending from the motor over the several pulleys are the belts 22, 23 and 24 for driving the belt 17. The rolls 18 and 19 are journaled in suitable bearings at the top and bottom of the frame respectively, and where the drying belt passes off the heating drum 20 there is a belt tightener 25, said tightener being pivoted on the side pieces a of the frame and free to rest its weight on the belt, thereby causing the same to be depressed in such a manner as to cause any prints that adhere to the belt to drop therefrom. The heating drum has a metal periphery as indicated at 26 over which there is a layer of heat absorbing material 27, and which latter material is covered with a suitable material to absorb the moisture in the prints without injuring them.

Suspended from the top frame of the machine is a chute 30, rods 31 at the corners thereof connecting it with the frame and holding it in the proper position. This chute is so inclined as to deliver all of'the prints received thereby at a point far enough away from the drum to permit an.

bearings 36 upon which it rotates. The shaft is connected with the gas supply pipe 37 and it has arms 38 which support the burner 39. a pipe 40 extending from said shaft to the burner for the delivery of gas This burner is of the well known Bunsen type having an air mixer at il, and a plurality of jets at 42, and the drum is provided with a series of end openings 20' and two large openings 20 for the supply of air to the burner.

The operation of the machine is as follows: The motor having been started the belt 17 is slowly drawn around the drum 2(1), operators at each side of thebelt placing the prints to be dried. thereon under the drum :tace down, thus curling them opposite to the way the tendency of the coating thereon tends to curl them. its the prints pass around the drum they are dried and such or" them as may stick thereto are scraped off by the lip 32, while such of them as may stick to the belt are caused to fall therefrom when the belt passes under the belt tightener.

lln Figs. 6 and Y there is shown an electrical heating element for the drying drum. in this form of the heating drum, the drum is indicated at 50, the supporting shaft at 51 and the electrical contact rings at 52 and 53, the latter being suitablyfinsulated from each other and from the shaft in a well known manner. The frame for the support is shown at 54- and it has a bracket 55 of insulating material extending therefrom for the support of the contact brushes 55 and 57, a cable 58 leading from the conductors thereto. The collecting rings are suitably connected with a heating element consisting of a layer of asuitable resistance wire 59 embedded in the surface of the drum 50. This drum has a heat insulatin material 60 over which the wire 59 is placed thick enough to prevent an undue loss of heat on the inner surface of the drum, and said wire is covered with a suitable insulating material 61 over which the layer of absorbent material 62 is placed.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States, is as follows, modifications within the scope of the claims being expressly reserved:

1. A printdrier comprising a drum, means to heat said passing around said drum, a pair of spaced rollers around which said apron passes, a chute between the two runs of the apron, and means to remove the prints from the drum and discharge them into said chute.

2. in a print drier, a drum, means to heat said drum, an endless apron passing around said drum, a pair cit-rollers around which said apron passes, a chute between the two runs of the apron, means to discharge the prints from the drum into said chute and means to cause the prints adheringto the apron to be removed therefrom above said chute.

drum, an endless apron,

in a print drier, a revoluble drum, means to heat said drum, an absorbent covering for sald drum, an endless apron passing around said drum, a pair of rollers over which said apron passes, a chute between the two runs of the apron, means to discharge prints from the drum into said chute, means to cause the prints adhering to the apron to fall into said chute, and a motor for driving the drum at a substantially constant speed.

4. lln a print drier, a revoluble drum, means to heat said drum, an endless apron passing; around the drum, rollers over which said apron passes, an inclined chute between the two runs of the apron adapted to discharge prints falling thereinto at a distance from the drum, means to discharge the prints into said chute, and a belt tightener above the apron to cause prints adhering thereto to fall into said chute.

5. In a print drier, a revoluble drum, means to heat said drum, an absorbent covering therefor, an endless absorbent apron extending around the drum, a pair of rollers spaced away from each other at substantially the diameter of the drum, and about which an endless apron passes, an inclined chute adapted to deliver prints falling thcreinto at a distance from the drum, means to remove prints Irom the drum and deliver them to the chute, a pair of links, and a roller pivoted in said links and bearing upon the top of the drum and aprons for loosening prints therefrom.

6. A print drier comprising a drum having an absorbent surface, means to heat the same, an endless apron passing around said drum and having its upper and lower runs spaced apart subtantially the diameter of the drum to afiord a working surface on the lower apron run, and a chute between the two runs to collect the prints as they drop from the apron.

7. A print drier comprising a drum having an absorbent surface, means to heat the same, an endless apron passing thcrcover, rollers to hold its runs separated, a belt tightcncr bearing on the upper apron run adjacent the drum, a laterally extending chute between the apron runs, and a scraper extending from the edge of the chute to and bearing on the drum.

In testimony whereof I have hereunto set my hand this 26 day of September A. D. 1913, in the presence of tho two subscribed witnesses BEVERLY Y. MORRIS. Witnesses:
